A technique for accessory cervical heart transplantation in rabbits and rats.

A surgical method for accessory cervical heart transplantation in rabbits and rats has been developed and the procedure is described in detail. For blood vessel anastomosis the method employs an extra-luminal teflon prosthesis. This non suture technique is found to be easy, quick and reliable in the hands of an operator without experience in microsurgery. The most frequent postoperative complication is thrombosis of the carotid artery occuring in 30 per cent of the rabbit recipients and 10–15 per cent of the rats. The superficial cervical localization of the transplant is found to be advantageous for control with function of the heart, and for exact determination of endpoint of the rejection process.
